UNITED STATES PATENT- Orrion.

FRANK HARVEY ZENT, OF COLUMBUS,OHIO, ASSIGNOR OF ONE-HALF TO D. J.MINTON, OF SAME PLACE.

SPECIFICATION forming part of Letters latent No. 580,824, dated April13, 1897. Application filed September 21, 1896. Serial No. 606,512. (Nomodel.)

To all whom it may concern.-

Be it known that I, FRANK HARVEY ZENT, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented certain new and useful Improvements in Coupling-Pins; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of my invention is to provide an improved pin for use inconnection with the type of car-coupling of which that popularly knownas the J annoy is an illustration. Pins as heretofore constructed havebeen objectionable'because of their liability to be jolted or worked outof their seats.

In the annexed drawings, Figure 1 illustrates an elevational view of thelatch side of the pin. Fig. 2 is an elevational view looking at theright-hand side of what is shown in Fig. 1. Fig. 3 is a side view of thecap and latch, and Fig. 4 is an elevational View of the right-hand sideof what is shown in Fig. 3.

The characterl on the drawings designates the main portion or body ofthe pin, which has an offset portion 2, with its base inclined, as shownat 3.

The upper portion of the pin is hollow, and upon this fits a cap 4,having a downwardlyextendingprojection 5, upon which is pivoted a latch6, the point of which works in and through a hole 7 in the face of theoifset 2. The projection 5 is made with avertical slot 8, through whichand the sides of the body cap to the body portion 1.

of the pin is passed a bolt 9, that secures the This slot allows aslight vertical play of the cap with respect to the body of the pin, sothat the cap may be lifted to pull the point of the latch into the hole,thereby permitting the free movement of the pin in its seat in thedraw-bar. The cap has at its top an eyepiece 10, by which the pin maybeoperated either by hand or by means of a cranked lever extending to theside of the car.

When the pin is lifted at the eyepiece 10, the latch 6 is drawn in andthe pin may be dropped into its place in the draw-bar. The weight of.the cap will then project the end of the pin under a shoulder in thedraw-bar and prevent its being jolted or worked up or otherwise removeduntil purposely done so by hand.

What I claim, and desire to secure by Letters Patent, is-

The herein-described pin for car-couplings comprising a body portion 1having a hole '7, and a cap 4 having a slotted projection 5, a latch 6pivoted to said projection, and a bolt passed through the slot orprojection 5 and engaging the walls of the pin, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK HARVEY ZENT.
